https://otter-waiver.usefulapi.io/mcp.claude mcp add --transport http otter-waiver https://otter-waiver.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Otter Waiver credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/otter-waiver/
On first connect you provide the Client ID and Client Secret (app.ottersign.com → Settings → Account and Preferences → API keys, use Show). The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.

Pro covers this server only. Subscribe with otterwaiver_upgrade (it returns a Stripe Checkout link). Cancel any time with otterwaiver_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running otterwaiver_upgrade before then undoes the cancel.
